When you change a wheel, remove any rust
or dirt from the places where the wheel
attaches to the vehicle. In an emergency,
you can use a cloth or a paper towel to do
this; but be sure to use a scraper or wire
brush later, if needed, to get all the rust

It is designed to stop the spare tire from suddenly
falling off your vehicle. For the secondary latch
to work, the spare tire must be installed with
the valve stem pointing down. SeeStoring a Flat
or Spare Tire and Tools on page 533.
{CAUTION:
Before beginning this procedure read all
the instructions. Failure to read and follow
the instructions could damage the hoist
assembly and you and others could get
hurt. Read and follow the instructions
listed next.

Step 6.
2. If it is visible, rst try to tighten the cable by
turning the wheel wrench clockwise until you
hear two clicks or feel it skip twice. You
cannot overtighten the cable.
